Hi, my motherboard requires RIMMs, but my specification sheet for my computer says I have PC800 RDRAM inside my computer right now? It is only 128mb, and I want to put in either 128x2 in the two empty slots, or remove the existing (I assuming 64x2) 128mb and then in total add 128x4mb in. Would these [COLOR="Olive"]SAMSUNG KMMR16R88AC1-RK8 800-45 100[/COLOR] RAM [128mbx2] work in my system? I'm not sure whether I need RDRAM or RIMMs or whether they are in fact one in the same? Please help - this is my motherboard info. [URL]http://www.uktsupport.co.uk/pb/mb/evergreen2.htm[/URL] Oh and can I mix and match sizes within their respective pairs? And can I mix and match ECC and non-ECC, again within respective pairs? Thank you very much in advance!
